Hello,

Anyone here running on 20" rims on the H3? What would be the proper tire size for the H3 on 20 inchers?  Is it 305/50 20?

thanks!
Ken

A nice little utility for getting as close as you can to stock height/etc for speedo calcs :)

275/65/20 right?  I may go with 256/65/20.  Its still the right diameter but a smaller foot print(width).  Maybe I''ll save some gas.[:)]

According to the tire calculator, the 275/55 20 would be a better size as it is only 1.1% slow in the speedo reading.

If you go 275/65 20, that''s 3% too slow.  So speedo reading 60mph you are really going 64.3mph

Keep in mind too Kendrick, that you CAN recalibrate the speedo with programmers (Hypertech etc).
